Transforming a fresh pineapple into delectable grilled skewers is a straightforward process. Follow these detailed steps to achieve perfectly caramelized, juicy, and flavorful results every time. Remember, grilling is as much an art as a science, so feel free to adjust cooking times based on your grill’s specific heat and your desired level of char.

1. Prepare the Pineapple:
   • Begin by carefully cutting your pineapple. Lay the pineapple on its side on a sturdy cutting board. Using a large, sharp chef’s knife, slice off the top crown and the bottom base, creating two flat surfaces.
   • Stand the pineapple upright on one of the flat ends. Carefully slice downwards, following the contour of the pineapple, to remove the tough outer skin. Rotate the pineapple and continue slicing until all the skin is removed. Don’t worry if a few “eyes” (the small brown spots) remain; you can remove these individually with the tip of your knife or a pineapple corer tool later, or simply cut around them when dicing.
   • Once peeled, you have a few options for coring. You can slice the pineapple into 1-inch thick rounds, then use a small round  cookie cutter or a knife to remove the tough central core from each slice. Alternatively, quarter the pineapple lengthwise, then slice away the V-shaped core from each quarter.
   • Cut the cored pineapple flesh into uniform 1 to 1.5-inch chunks. Uniformity is key here, as it ensures even cooking on the grill. Aim for pieces that are substantial enough to hold up on the skewers and during grilling. You should have about 4-5 cups of pineapple chunks.
2. Soak Wooden Skewers (if using):
   • If you’re using wooden or bamboo skewers, place them in a shallow dish or a tall glass filled with water. Ensure they are fully submerged. Let them soak for at least 30 minutes. This crucial step prevents the skewers from catching fire and burning to a crisp on the hot grill. Metal skewers do not require this step.
3. Prepare the Glaze/Coating:
   • In a small mixing bowl, combine the packed light brown sugar, ground cinnamon, and optional ground nutmeg and pinch of salt. Whisk them together thoroughly to ensure the spices are evenly distributed throughout the sugar.
   • In a separate small bowl, melt the coconut oil if it’s solid. You can do this in the microwave in short 10-15 second bursts or in a small saucepan over low heat.
   • If using, add the freshly squeezed lime juice to the melted coconut oil.
4. Coat the Pineapple:
   • Place the pineapple chunks in a large mixing bowl. Drizzle the melted coconut oil (and lime juice, if using) over the pineapple. Toss gently with a spoon or your hands to ensure each piece is lightly coated. The oil will help the sugar mixture stick and will also prevent the pineapple from sticking to the grill.
   • Sprinkle the brown sugar and spice mixture over the oiled pineapple chunks. Toss again, very gently, until all the pineapple pieces are evenly coated with the sweet and spicy mixture. Be thorough but gentle to avoid mashing the pineapple.
5. Assemble the Skewers:
   • Carefully thread the coated pineapple chunks onto your prepared skewers. Leave a small space (about 1/4 inch) between each piece of pineapple. This allows the heat to circulate around each chunk, promoting even cooking and caramelization on all sides.
   • Don’t overcrowd the skewers. Typically, 4-6 pieces of pineapple per skewer is a good amount, depending on the length of your skewers and the size of your pineapple chunks. Leave some space at both ends of the skewer for easier handling on the grill.
6. Preheat the Grill:
   • Preheat your outdoor grill or indoor grill pan to medium-high heat, around 375-450°F (190-230°C).
   • Clean the grill grates thoroughly with a grill brush. This prevents sticking and ensures you get those beautiful, clean grill marks. Once clean, you can lightly oil the grates by wiping them with a paper towel dipped in a high-heat cooking oil (like canola or vegetable oil), using tongs for safety.
7. Grill the Pineapple Skewers:
   • Carefully place the assembled pineapple skewers directly onto the preheated and cleaned grill grates.
   • Grill for approximately 3-5 minutes per side. The exact cooking time will vary depending on the heat of your grill and the thickness of your pineapple chunks. You are looking for the pineapple to become tender, heated through, and develop beautiful, dark golden-brown grill marks. The sugar will caramelize, creating a slightly crispy and incredibly flavorful exterior.
   • Use tongs to turn the skewers, ensuring all sides get some time on the heat. Watch them closely, as the sugar can burn if the heat is too high or if they are left unattended for too long. You want caramelization, not charring to the point of bitterness.
   • The pineapple should be tender enough to easily pierce with a fork but still hold its shape. The aroma will be incredibly inviting – sweet, smoky, and spicy.
8. Rest and Serve:
   • Once the pineapple skewers are perfectly grilled, carefully remove them from the grill using tongs and place them on a clean platter or serving dish.
   • Allow them to rest for a few minutes before serving. They will be very hot! This short resting period also allows the juices to redistribute slightly.
   • Serve warm and enjoy the delightful combination of sweet, tangy, smoky, and spiced flavors.

By following these instructions, you’ll be well on your way to enjoying some of the best grilled pineapple skewers you’ve ever tasted. The key is good quality pineapple, careful preparation, and attentive grilling.
